The 2017 TMDL Performance Report compiles accomplishment reporting results submitted by TMDL Implementers to the Water Board, NDEP and TRPA. Accomplishments are summarized according to urban and non-urban source categories. Urban stormwater accomplishments as estimated annual average fine sediment, nitrogen and phosphorus load reductions and associated Lake Clarity Credit awards, while non-urban source accomplishments are reported using a set of relevant performance measures that quantify the extent of the activities undertaken to improve water quality.

This document is the report that summarizes the Numeric Target, Pollutant Source Analysis, Load Allocations, Implementation Plan, Adaptive Management Process, and the required Regulatory Analysis for the Lake Tahoe Total Maximum Daily Load (Lake Tahoe TMDL). It is an approximately 350 page, 15 chapter document.
This Final EPA approved version for Nevada has been revised from the California adopted version for which EPA approval was gained the same day. The revisions were necessary to correct errors, clarify Nevada’s regulatory structure and approach to implementation and emphasize that the proposed implementation timelines may need to be adjusted for a variety of reasons, but particularly the availability of future funding. The errata sheet indicates all the differences between these versions.

A simple, repeatable, precise and objective field observation protocol to assess road condition. Accepted as an alternative to Road RAM in 2018, Highway RAM is performed in the highway road shoulder, thereby improving user safety and reducing time and costs to collect measurements.

Establishes and provides guidance related to the annual process Urban Implementers perform to 1) consistently estimate expected load reductions, 2) register or document the pollutant controls and conditions that are expected to result in the estimated load reductions, 3) inspect on-the-ground conditions to verify the conditions used to estimate load reductions are being maintained, and 4) declare the credits to demonstrate compliance with permits and agreements. Version 2.1 corrects typographical and grammatical errors from Version 2.0.

The Miles of Roads Decommissioned or Retrofitted TMDL Performance Measure tracks the miles of paved and unpaved roads in the forest uplands that are decommissioned or retrofitted to reduce stormwater pollution. Updated 12/10/15.

The Miles of Roads Inspected and Maintained TMDL PM tracks the miles of permanent paved and unpaved forest roads that are inspected and/or maintained to reduce stormwater pollution from the Forested Uplands each year.

The Acres of Disturbed Area Restored, Enhanced or Created TMDL PM tracks the total acres of land in the Forested Uplands with compacted soil, disturbed vegetation and/or impacted hydrology that is restored, enhanced or created each year.

The Parcels with Stormwater Retrofits TMDL PM tracks the number of developed parcels on property belonging to large, public landowners in the Forested Uplands that are retrofitted with best management practices (BMPs) that emphasize removal of fine sediment particles and nutrients.

The Linear Feet of Stream Channel Restored or Enhanced TMDL PM tracks the linear feet of stream channel restoration and enhancement projects implemented to reduce stream channel erosion and contributions of pollutants from within the stream channel on Tahoe Basin streams each year.

The 2014 Synthesis of Findings & Program Adjustment Recommendations Memo considers and evaluates TMDL Program operations, achievements, challenges, new relevant scientific findings and stakeholder input. The 2014 Memo includes new findings and addresses comments provided by stakeholders in review of the 2010-2013 Memo.

The Synthesis of Findings and Program Adjustment Recommendations Memo is released each summer by TMDL Program Managers. It provides an overview of new, important and relevant scientific and technical information and findings that may support or are informing potential adjustments to the TMDL Program or related policies. The document also contains a set of actionable recommendations proposed by TMDL Program Managers to adjust the TMDL Program, including its management strategies or its guiding policies.

The List of Information Needs is a tool to help 1) communicate and track research and applied science needs, 2) track and respond to stakeholder feedback in an organized and transparent manner and communicate TMDL Program Manager identified priority needs to stakeholders. The List of Information Needs is populated by TMDL Program Managers who add stakeholder feedback to the list throughout the year. TMDL Program Managers refer to the list to draft the annual Synthesis of Findings & Program Adjustment Recommendation Memo.

The Program Adjustments List contains recommended adjustments to operational protocols or technical tools related to TMDL implementation. TMDL Program Managers use the list to track, organize, prioritize and make recommendations for program adjustments. The Program Adjustments List is populated by TMDL Program Managers who add stakeholder feedback to the list throughout the year. TMDL Program Managers reference the list when drafting the Synthesis of Findings & Program Adjustment Recommendation Memo.
